Hello, My R package interpolation is successfully installed on numerous systems (even with Valgrind), but the installation fails on Mac. In view of this temporary compilation report, would you know whether this is due to a too old version of mpfr maybe? There were some errors with an outdated version of mpfr but I'm not sure there are the same. |

Is the version of clang available somewhere? It looks like https://bugs.llvm.org/show_bug.cgi?id=43266 , but that was supposedly fixed a while ago. |

Apparently that means LLVM-6, while the highly similar bug report mentions a fix in LLVM-9 (probably Xcode 11.4). If there is a way to use a more recent compiler, that would be best. Otherwise, you could try to patch GMP with -#define mpz_sgn(Z) ((Z)->_mp_size < 0 ? -1 : (Z)->_mp_size > 0)
+#define mpz_sgn(Z) (((Z)->_mp_size < 0) ? -1 : ((Z)->_mp_size > 0)) (and similar for the next 2 lines) to see if that helps work around this compiler bug. |
